In a large bowl mix chopped apples, cinnamon and nutmeg, set aside. 

In a large skillet cook your sausage and crumble it as you go. Once cooked remove and place on a paper towel lined plate.

Next add 2 tablespoons butter, salt and pepper and chopped potatoes to the skillet, cook until just fork tender, 8-10 min.

Add sausage and potatoes to a baking dish, set aside.

Add your chopped apples to the skillet with remaining 2 tbsp butter and cooked until just browned 5 min. Once those have cooked you want to toss the cooked sausage potatoes and apples together in the baking dish, and lightly cover with cheese. 

Bake at 350 for 12-15 min or until cheese is melted.
